The use of geographical information systems in determining the level of erosion hazards in the farm watershed sub-region using the universal soil loss equation method

Introduction

Watersheds play a vital role in agricultural land, serving as the primary water supplier for farming activities. However, these watersheds are also susceptible to erosion, which can damage soil structure and reduce agricultural productivity. Erosion can occur due to natural factors and human activities. In an effort to predict and analyze the level of erosion hazards, geographical information systems (GIS) offer an effective approach by utilizing spatial data. The Universal Soil Loss Equation (USLE) method is a suitable tool for determining the level of erosion in the Farmers' sub-watershed. This article discusses the use of GIS and the USLE method in determining the level of erosion hazards in the farm watershed sub-region.

Utilization of GIS and USLE

Geographic information systems are designed to collect, store, and analyze phenomena related to geographical locations. Through GIS, researchers can analyze spatial-based data, such as satellite imagery and digital elevation model (DEM) data, to obtain accurate information about land conditions. The USLE method is a widely used approach for predicting soil erosion, and it takes into account various parameters that affect erosion, including vegetation, soil slope, and soil type. By utilizing the USLE method, researchers can estimate the rate of erosion and identify areas prone to severe erosion.

The main purpose of this study is to determine the level of erosion hazards in the Farmers' sub-watershed. This study was conducted by conducting field observations to collect necessary data, as well as using the USLE approach to calculate the rate of erosion and estimate the impact. The results of this study can provide valuable insights for decision-makers in planning sustainable natural resource management policies.

Methodology

The study area was the Farmers' sub-watershed, which is located in a rural area. The study used a combination of field observations and GIS analysis to collect and analyze data. The field observations involved collecting data on soil type, vegetation cover, and soil slope. The GIS analysis involved using satellite imagery and DEM data to create a spatial database of the study area. The USLE method was used to calculate the rate of erosion and estimate the impact of erosion on the soil.

Results and Findings

The results of the study showed that the Farmers' sub-watershed had various levels of erosion hazards. From the data obtained, the hazard level of severe and very severe erosion was identified at several observation points. Point A10 recorded the lowest erosion rate, which was 14.81 tons/ha/year, while point A1 had the highest erosion rate with a value of 7823.56 tons/ha/year. The significant difference between the rate of erosion at both points indicates the influence of environmental factors and different human actions in each location.

Analysis and Implications

Based on the results obtained, it is essential to develop a mitigation strategy to reduce the negative impact of erosion. Implementation of environmentally friendly land management practices, planting vegetation, and making terraces can be a solution to maintain soil quality and reduce the rate of erosion. GIS can continue to be used as a monitoring tool to analyze the changes that occur in the Farmers' Sub-Das, as well as designing a better management plan in the future.

Conclusion

The use of GIS and the USLE method in determining the level of erosion hazards in the farm watershed sub-region is a valuable approach for predicting and analyzing erosion. The results of this study can provide valuable insights for decision-makers in planning sustainable natural resource management policies. The implementation of environmentally friendly land management practices and the use of GIS as a monitoring tool can help to reduce the negative impact of erosion and maintain soil quality.
