Topography & Soil

The City of San Carlos lies on a 0-3% slope, relatively flat. On the southwestern is the Agno River and on the northern part of 10.58 kilometres away is the West Philippine Sea. The City is being traversed by San Juan River; the Marusay River on the northeastern; and various water tributaries. The City of San Carlos situated at the low lying area of central Pangasinan was subjected to frequent severe flooding during rainy season especially when there are typhoons, which brought about by the overflow of the Agno River Basin by the release of voluminous water coming from the Ambuklao and Binga Hydro Power Plants. However, only the barangays situated within the dike are most affected (map No.8). The urban center is situated in slightly higher ground and is free from flooding except on occasionally heavy downpour, that it immediately subsides, Bodies of Water.

The soil of Pangasinan Province represent a wide range in age or stage of development from young soils of comparatively recent deposits of alluvial material to old soils with some accumulations of limestone precipitates and colloidal material in the subsoil and a firmly cemented material or hardpan in the lower subsoil or in the substratum. The soils considered important agriculturally are those formed from materials which are of rather recent deposits representing the young immature stages of development (Alicante et.al., 1940, p. 21). The largest type of soil present in Pangasinan is so called San Manuel Series. This series is a continuation of the soil series established in the northeastern part of Tarlac and this type of soil is suited for agricultural purposes. The soil consists of pale-brown, light gray to pale-brownish gray surface soil, and a brown to grayish-brown subsoil ranging in depth from 70 to 110 centimeters.
