Title:

EFFECTS OF HIGHWAY CONSTRUCTION ON SEDIMENT LOADS IN STREAMS

Accession Number:

00236636

Record Type:

Component

Abstract:

HIGHWAY CONSTRUCTION IS OFTEN HELD RESPONSIBLE FOR SIGNIFICANT INCREASES IN SUSPENDED SEDIMENT YIELD IN ADJACENT STREAMS. LITTLE FACTUAL INFORMATION HAS BEEN AVAILABLE TO OBJECTIVELY EVALUATE THE VALIDITY OF THIS ACCUSATION. A STUDY HAS BEEN CONDUCTED TO OBTAIN THE RELATIONSHIP BETWEEN HIGHWAY CONSTRUCTION AND CHANGE IN SUSPENDED SEDIMENT YIELD IN STREAM SYSTEMS. A FIELD INVESTIGATION WAS CARRIED OUT IN A DRAINAGE BASIN, THROUGH WHICH AN INTERSTATE HIGHWAY WAS BEING CONSTRUCTED, TO COLLECT DATA NECESSARY FOR THE DEVELOPMENT OF A PREDICTION METHOD. THIS PAPER DESCRIBES AN INVESTIGATION OF THE EFFECTS OF RAINFALL, CONSTRUCTION PHASES, AND PROXIMITY OF CONSTRUCTION TO THE STREAM SYSTEM ON THE QUANTITY OF SEDIMENT TRANSPORTED. FIELD DATA FOR THE ANALYSIS WERE COLLECTED AT FOUR RAIN GAUGE SITES, AT EIGHT STREAM STATIONS, AND OVER APPROXIMATELY 5 MILES OF HIGHWAY CONSTRUCTION. A REGRESSION EQUATION RELATING THE OBSERVED VARIABLES TO THE SEDIMENT YIELD IS PRESENTED AND DISCUSSED. RESULTS INDICATE THAT THE SEDIMENT SUPPLY TO THE STREAMS INCREASES WITH RAIN ENERGY, CLEARING AND GRUBBING, EMBANKMENT WORK, AND PROXIMITY OF CONSTRUCTION TO STREAM. IT IS CONCLUDED THAT THE RESULTS OF THE STUDY MAY BE EMPLOYED AS A MEANS OF PREDICTING WHETHER HIGHWAY CONSTRUCTION WOULD BE A SIGNIFICANT POLLUTION SOURCE FOR A PARTICULAR SITE, A CRITERION TO BE CONSIDERED BY AN ENGINEER DURING LOCATION STUDIES, AND A BASIS TO EVALUATE THE EFFECTIVENESS OF ATTEMPTS TO CONTROL SEDIMENT YIELD FROM CONSTRUCTION AREAS. /AUTHOR/
