as water is directed in to the bank by debris lodged in the channel(passive) are often causedStream bank erosion problems

often(passive) are ... causedStream bank erosion problems

quantity problemsresultsin flooding ... stream bank erosion

While stormdrains and sewers can capture rain that falls on these impervious surfaces , they also accelerate the flow of rainwatercausingstream bank erosion and flooding

Recent flooding from Hurricane Irene hereresultedin much stream bank erosion

very low base flow conditionscan leadto significant stream bank erosion

These alterationshave also leadto increased stream bank erosion

When it reaches the nearest stream , the runoff and accumulated trash and pollutants enter the waterway too quicklycausingstream bank erosion and flooding

then creekscausingincreased erosion of stream banks

by storm water runoff from the landfill ( and upstream development(passive) caused bysignificant stream bank erosion

by continuous cattle access(passive) caused byriver and stream bank erosion

Ground Saturation Stormwatercauseserosion , stream bank instability

Urban runoffmay causeExcessive stream bank erosion

Hydrologic Alteration(passive) caused byform stream bank erosion

Heavy rains in December 2008 and February 2009had causedextensive stream bank erosion

the drop in creek bedhas causedthe erosion of the surrounding stream bank

increases in runoff rate and volume ... , as well as other changes such as removal of trees / vegetation along our streamsresultingin stream bank erosion

These channel widening processesresultin accelerated stream bank erosion

Increased runoff rates due to removal of vegetation , soil compaction and construction of roads and other impervious surfacescan causestream bank erosion

flow fluctuations driven by storm events as well as by stream maintenance measures , such as woody debris removal(passive) is caused byStream bank erosion

by the flood of 2007(passive) caused byCreek bank erosion

When land use changes , such as clearing land for agriculture , occur in a watershed , runoff increases and thus the stream channel adjusts to accommodate the additional flowcausingstream bed erosion

Increased runoffhas resultedin stream bank erosion

may flow fastercausingstream bank erosion

The extra water velocity generates high peak flows during stormscausingerosion on stream banks

The storm water runoff can enter the stream with enormous forcecausingstream bank erosion

the power of these flowscan causestream bank erosion

And , high velocities continueto causestream bank erosion

removal of vegetation(passive) is caused byThe stream bank erosion

by heavy stormwater(passive) caused bystream bank erosion

the extraction of any material ... any streammay leadto the erosion of the stream bank
