Hydrological Processes in a Small Research Watershed under Forest Coverage in the Coast of Chiapas, Mexico

In the hydrological watershed, some natural processes take place in which interaction of water, soil, climate and vegetation favors capture water. The present study aimed to evaluate preliminary information regarding response water balance a small research watershed with tropical forest cover (15°01'44''N 92°13'55''W, 471 m, 2.3 has). Events precipitation, direct runoff, infiltration rate baseflow were performed. amount, duration intensity rainfall events recorded use pluviograph. Surface runoff was quantified an established gauging station, H-type device horizontal mechanical limnograph. Runoff base flow measured at station using volume-time method. Infiltration triple ring infiltrometer, taking two measurements upper part lower microbasin. Evapotranspiration amount entering leaving watershed. period, annual 4417.6 mm distributed over 181 recorded; about 70% storms showed intensities 20 mm·h-1. total 345.8 caused by half events, represents 7.8% rain; 77% sheets 5 average specific 20.7 L·s-1·ha-1 maximum 113.6 L·s-1·ha-1.
