Abstract (in english)
   This report examines climatological and hydrological data collected at Animal Park Experimental Catchment, Almora, U.P., between 1989 and 1995. Preliminary geochemical tests yield results that may be fairly typical for a relatively undisturbed forest head water. This is a near neutral pH, high conductivity (K25/uS/cm) stream. Base flow concentrations of Ca 2+, K+ and Mg 2+ are relatively low for the region, as is sulphate. Nitrate and ammonia show peaks that may be related to land management activity. The proportion of dissolved to suspended load is high (1.27:1). The construction of checkdams in the later 1970s has shifted the physical/chemical load ratio by trapping sediment within the basin. Statistical analyses show that suspended and bed-load sediment transport are strongly correlated with runoff and hence transport-limited. By contrast, dissolved load transport is supply-limited. Dilution effects create a negative relationship with runoff and positive relationship with evaporatio
