A visual and numerical aid to detecting surface water connectivity points in deltaic floodplains.

In cold regions deltas influenced by semi-arid climates, such as the Peace-Athabasca Delta (PAD) in western Canada, surface water connectivity influences aquatic conditions by offsetting evaporative losses that are generally greater than precipitation inputs (Kääb et al., [6]; Lesack & Marsh, [7]; Peters, Prowse, Marsh, et al., [11]). This information is necessary to arrive at key hydrological information for an inland basin in question: (i) total basin area delineation, (ii) runoff contribution areas to the water body, (iii) maximum water surface extent, and (iv) frequency of surface water connectivity. TAKE AWAY MESSAGES We employed a visual and numerical aid to detect ice-jam and open-water condition surface water connectivity points in a sector of the Peace-Athabasca Delta.
