Effects of sparse rigid stem vegetation coverage on hydrodynamic characteristics of overland flow in a gentle slope area

Abstract Vegetation plays a vital role in natural ecosystems, especially in soil and water conservation.

520			\|a Abstract Vegetation plays a vital role in natural ecosystems, especially in soil and water conservation. The accurate estimation of hydraulic parameters of overland flow is an important means to understand the hydraulic characteristics of overland flow and soil erosion. However, there is limited research on sparse stem vegetation coverage under gentle slope conditions. This study aims to understand the inherent laws that control overland flow structure under sparse vegetation cover. To achieve this, hydraulic characteristics of surface runoff on slopes covered by stem vegetation were quantified for seven flow discharges (Q) (0.0313–0.5203 $ m^{3} $/min), four slopes (S) (0.0–3.0%), and six stem coverage degrees (Cr) (0.07–0.72%) through a laboratory flume. The results showed that the same impact factor has different degrees of influence on different hydraulic parameters of overland flow resulting in varied hydrodynamic characteristics. In this study, for the vegetation coverage of sparse stems, under the condition of the flat slope, Cr is the dominant factor affecting Froude number and Manning roughness coefficient, whereas Q is the dominant factor affecting flow velocity and Reynolds number. However, under the condition of the non-flat slope, Cr is the dominant factor affecting Manning roughness coefficient, Q is the dominant factor affecting Reynolds number, and S is the dominant factor affecting the velocity and Froude number.

The accurate estimation of hydraulic parameters of overland flow is an important means to understand the hydraulic characteristics of overland flow and soil erosion. However, there is limited research on sparse stem vegetation coverage under gentle slope conditions. This study aims to understand the inherent laws that control overland flow structure under sparse vegetation cover. To achieve this, hydraulic characteristics of surface runoff on slopes covered by stem vegetation were quantified for seven flow discharges (Q) (0.0313–0.5203 $ m^{3} $/min), four slopes (S) (0.0–3.0%), and six stem coverage degrees (Cr) (0.07–0.72%) through a laboratory flume. The results showed that the same impact factor has different degrees of influence on different hydraulic parameters of overland flow resulting in varied hydrodynamic characteristics. In this study, for the vegetation coverage of sparse stems, under the condition of the flat slope, Cr is the dominant factor affecting Froude number and Manning roughness coefficient, whereas Q is the dominant factor affecting flow velocity and Reynolds number. However, under the condition of the non-flat slope, Cr is the dominant factor affecting Manning roughness coefficient, Q is the dominant factor affecting Reynolds number, and S is the dominant factor affecting the velocity and Froude number.

The accurate estimation of hydraulic parameters of overland flow is an important means to understand the hydraulic characteristics of overland flow and soil erosion. However, there is limited research on sparse stem vegetation coverage under gentle slope conditions. This study aims to understand the inherent laws that control overland flow structure under sparse vegetation cover. To achieve this, hydraulic characteristics of surface runoff on slopes covered by stem vegetation were quantified for seven flow discharges (Q) (0.0313–0.5203 $ m^{3} $/min), four slopes (S) (0.0–3.0%), and six stem coverage degrees (Cr) (0.07–0.72%) through a laboratory flume. The results showed that the same impact factor has different degrees of influence on different hydraulic parameters of overland flow resulting in varied hydrodynamic characteristics. In this study, for the vegetation coverage of sparse stems, under the condition of the flat slope, Cr is the dominant factor affecting Froude number and Manning roughness coefficient, whereas Q is the dominant factor affecting flow velocity and Reynolds number. However, under the condition of the non-flat slope, Cr is the dominant factor affecting Manning roughness coefficient, Q is the dominant factor affecting Reynolds number, and S is the dominant factor affecting the velocity and Froude number.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Overland flow</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Sparse vegetation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Vegetation coverage</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Gentle slope</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Hydrodynamic characteristics</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Soil and water conservation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhang, Shengtang</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Chen, Si</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Liu, Ming</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Arabian journal of geosciences</subfield><subfield code="d">Berlin : Springer, 2008</subfield><subfield code="g">14(2021), 15 vom: 21.

title_auth	Effects of sparse rigid stem vegetation coverage on hydrodynamic characteristics of overland flow in a gentle slope area
abstract	Abstract Vegetation plays a vital role in natural ecosystems, especially in soil and water conservation. The accurate estimation of hydraulic parameters of overland flow is an important means to understand the hydraulic characteristics of overland flow and soil erosion. However, there is limited research on sparse stem vegetation coverage under gentle slope conditions. This study aims to understand the inherent laws that control overland flow structure under sparse vegetation cover. To achieve this, hydraulic characteristics of surface runoff on slopes covered by stem vegetation were quantified for seven flow discharges (Q) (0.0313–0.5203 $ m^{3} $/min), four slopes (S) (0.0–3.0%), and six stem coverage degrees (Cr) (0.07–0.72%) through a laboratory flume. The results showed that the same impact factor has different degrees of influence on different hydraulic parameters of overland flow resulting in varied hydrodynamic characteristics. In this study, for the vegetation coverage of sparse stems, under the condition of the flat slope, Cr is the dominant factor affecting Froude number and Manning roughness coefficient, whereas Q is the dominant factor affecting flow velocity and Reynolds number. However, under the condition of the non-flat slope, Cr is the dominant factor affecting Manning roughness coefficient, Q is the dominant factor affecting Reynolds number, and S is the dominant factor affecting the velocity and Froude number. © Saudi Society for Geosciences 2021
