Applicability of three soil erosion models for burnt hillslopes was evaluated. The models were estimated with the data from plots established after tremendous wildfire occurred in the east coastal region. Soil erosion and surface runoff were simulated by the Water Erosion Prediction Project (WEPP) a...

토양침식을 정량적으로 산정하는 것의 목표는 무엇인가? | 토양침식의 위험도를 평가하고 침식조절방법을 결정하기 위해서 토양침식을 정량적으로 산정하는 것이 필요하다. 토양침식 및 토사유출 예측모형은 토사유출 영향인자들을 측정한 자료에 근거하여 만든 경험적인 모형과 침식의 역학적 과정을 모사한 물리적 산정모형으로 크게 구분한다. | |
토양침식 및 토사유출 예측모형을 구분하면 무엇이 있는가? | 토양침식의 위험도를 평가하고 침식조절방법을 결정하기 위해서 토양침식을 정량적으로 산정하는 것이 필요하다. 토양침식 및 토사유출 예측모형은 토사유출 영향인자들을 측정한 자료에 근거하여 만든 경험적인 모형과 침식의 역학적 과정을 모사한 물리적 산정모형으로 크게 구분한다. 1970년대 중반 이후 개발된 다양한 토양침식 모형의 구조는 농업 지역의 유출 및 토양침식에 작물의 재배방법과 윤작이 미치는 영향을 예측하기 위한 것이 지배적이었다. | |
WEPP의 입력자료의 분류 범주에는 무엇이 있는가? | WEPP의 구성은 일별 기후를 모의하기 위한 추계학적인 기상자료 모의발생, 수정 Green-Ampt 침투식을 토대로 한 침투 및 유출, 토양과 물의 상호작용, 식생 생장, 식생잔류물분해, 배수 등의 요소로 구성되어있다. 입력자료는 식생조건과 관리방법, 사면, 토양, 기후의 4가지 범주로 분류된다. 또한 모형은 경작지와 방목지, 연속강우와 단일호우 조건에 대해 적용할 수 있다(Flanagan and Nearing, 1995). |
