Soil Water Precipitation and Evaporation Infiltration Streamflow and Groundwater Hydrologic Statistics and Hydraulics Erosion and Sedimentation Soils for Environmental Quality and Waste Disposal . Physical . weather reduces the particle size of rocks and in doing so prepare the material for chemical weathering. The rate of all chemical reactions involving solids is determined by the amount of exposed surface area. These four drawing illustrates sequentially dividing particles into smaller particles. Assuming a dimension of 1 cubic centimeter . Syllabus, sequence of topics. Case study of Brushy Creek watershed . Hydrology as a science and as a profession. Hydrologic cycle and world water balance. Water as a physical substance. Readings: . For today – Applied Hydrology and Chapter 1. Syllabus, sequence of topics. Hydrology as a science and as a profession.

Soils support the growth of higher plants by providing a medium for plant roots and supplying nutrient elements that are essential to the entire plant.. Soil properties are the principal factor controlling the fate of water in the hydrologic system. Water loss, utilization, contamination and purification are all affected by the soil.. Runoff.
