We investigate to what extent the initial conditions (in terms of buoyancy and\ngeometry) of saline gravity currents flowing over a horizontal bottom\ninfluence their runout and entrainment capacity. In particular, to what\nextent the effect of the introduction of an inclined channel reach, just\nupstream from the lock gate, influences the hydrodynamics of gravity currents\nand consequently its potential erosion capacity is still an open question.\nThe investigation presented herein focuses on the unknown effects of an\ninclined lock on the geometry of the current, on the streamwise velocity, on\nbed shear stress, and on the mechanisms of entrainment and mass exchange.\nGravity currents were reproduced in the laboratory through the lock-exchange\ntechnique, and systematic tests were performed with different initial\ndensities, combined with five initial volumes of release on horizontal and\nsloped locks. The inclination of the upstream reach of the channel (the lock)\nwas varied from 0\u2009% to 16\u2009%, while the lock length was reduced by up to 1\u22154 of\nthe initial reference case. We observed that the shape of the current is\nmodified due to the enhanced entrainment of ambient water, which is the\nregion of the current in which this happens most. A counterintuitive relation\nbetween slope and mean streamwise velocity was found, supporting previous\nfindings that hypothesized that gravity currents flowing down small slopes\nexperience an initial acceleration followed by a deceleration. For the\nsteepest slope tested, two opposite mechanisms of mass exchange are\nidentified and discussed, i.e., the current entrainment of water from the\nupper surface due to the enhanced friction at the interface and the head\nfeeding by a rear-fed current. The bed shear stress and the corresponding\npotential erosion capacity are discussed, giving insights into the\ngeomorphological implications of natural gravity currents caused in different\ntopographic settings.<\/jats:p>","DOI":"10.5194\/esurf-7-377-2019","type":"journal-article","created":{"date-parts":[[2019,4,26]],"date-time":"2019-04-26T06:36:11Z","timestamp":1556260571000},"page":"377-391","source":"Crossref","is-referenced-by-count":6,"title":["Potential erosion capacity of gravity currents created by changing initial conditions"],"prefix":"10.5194","volume":"7","author":[{"given":"Jessica","family":"Zordan","sequence":"first","affiliation":[]},{"given":"Anton J.","family":"Schleiss","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0265-8581","authenticated-orcid":false,"given":"M\u00e1rio J.","family":"Franca","sequence":"additional","affiliation":[]}],"member":"3145","published-online":{"date-parts":[[2019,4,26]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","unstructured":"Ancey, C.: Gravity flow on steep slope, vol.
