WebJul 11, 2024 · Nationwide, soil erosion, nutrient loss, and the runoff of pesticides and other contaminants from America’s vast agricultural land base are the leading causes of water quality impairment. The impacts vary widely across the country, depending on farm types, conservation practices, soils, climate, topography, and other local conditions. WebHow does topography affect runoff? Steep slopes have high runoff water velocity . This increases its erosive energy (remember that erosive energy of runoff is a function of runoff velocity and volume). When the slope is longer (length), surface area for water collection also increases and therefore increases the run-off volume. onyx albums
