The CADIC’s Geological Resources Program will soon turn 40 years of fruitful development. During this period many projects were carried out and others remain to be implemented. In the course of time three generations of researchers have been formed. Mentioning names would be unfair to those that could be involuntarily omitted.An arroyo is a nearly vertically walled, flat floored stream channel that forms in fine, cohesive, easily eroded material. Arroyos can cut as deeply as 20 meters (65 feet) into the valley floor, are often wider than 50 meters (165 feet), and can be hundreds of kilometers long.

Often associated with flashfloods, an arroyo is a stream bed or dry creek that temporarily fills and flows after sufficient rainfall.The volcanic rocks of the Conejo Formation underlies much of the surrounding watersheds. The younger Tertiary sedimentary Modelo and Upper Topanga Formations flank the Conejo to the north and south. On the north slope of the Santa Monica Mountains where the Arroyo Conejo and Thousand Oaks are located, the Tertiary formations are gently folded.Geology divided the Arroyo Seco into three distinct sections with very different hydrologic characteristics: 1) the precipitous upper mountain watershed; 2) the Raymond Basin area including Pasadena and surrounding communities; and 3) the region below the Raymond Dyke M Arroyo, D Muir Wood, PD Greening.

"The main street of Silver City, New Mexico, is a drainage channel that was originally two or three feet lower than the adjacent ground. In 1887 this channel began to deepen, bridges were built for the crossing and a wooden drop structure was constructed to prevent further headward cutting.
We propose that arroyo dynamics are partially driven by sediment supply and the rate of channel aggradation, and that these systems must approach complete re-filling before they become sensitive to incision.
