Low water level<br />

Waterway geometrics:<br />

sharp curves, rocky bootom (bedrock) <strong>and</strong> river banks, submerged obstacles<br />

like hidden rocks, vessel wrecks, big boulders, etc., narrow channels<br />

not allowing the crossing <strong>of</strong> two vessels or overtaking, high bottom<br />

gradients with hidden tresholds, etc.<br />

Hydraulics <strong>of</strong> the<br />

waterflow<br />

Strong funnel shaped currents, strong turbulent currents, water upsruges,<br />

whirlpools, side ci = urrents from tributaries or side channels, etc.<br />

Location <strong>of</strong> the hazard<br />

upstream from important water intakes, upstream from big cities, upstream<br />

from important wetl<strong>and</strong>s, Tonle Sap <strong>and</strong> entrance <strong>of</strong> the Great<br />

Lake during flood season, upstream from special zones with protected<br />

species, etc.<br />

Navigation, traffic,<br />

communication,<br />

man-made obstacles, etc.<br />

traffic density <strong>and</strong> presence <strong>of</strong> high speed vessels, fishing nets across the<br />

river, dredging vessels <strong>and</strong> pontoons or moored barges in the channel,<br />

bad or no communication between vessels <strong>and</strong> shore, bad or no communication<br />

between vessels, damaged aids to navigation (beacons) or<br />

misplaced buoys, busy ferry crossings obstructing long haul traffic, piers<br />

<strong>and</strong> causeways from ports <strong>and</strong>/or terminals, absence or limited information<br />

on existing water levels <strong>and</strong> traffic density, low tension high voltage<br />

cables, etc.
