With the joint proposal the relief changes in the glacier forefield are investigated by bringing several scientific disciplines together. Theproject glaciology and geomorphology deals with the contribution of glaciers to the suspended load and bed load transport within theglacial stream. The focus is on the relationships of the interacting processes of meltwater production, glacier motion, supply of sediment from the catchment and the subglacial sediment transport (sediment cascade model). The subproject glaciology and geomorphology is closely connected to the other subprojects and is conducting fundamental research of intrasystematic feedbacks. The separation of surface and subglacial melting by measurements of the surface ablation and total volume changes derived from laser scans is new. The high temporal and spatial resolution of the measurements at the glacier tongue with a thickness of about 100 meters is new as well as the use of the vibroseismic at the temperate glacier tongue to investigate ice thickness and the properties of the zone of loosening.

结合多学科的研究成果，对冰川前场地形变化进行了研究。项目冰川学和地貌学研究冰川对冰川河流中悬浮荷载和河床荷载运输的贡献。重点研究融水产生、冰川运动、流域沉积物供应和冰下沉积物运输（沉积物级联模型）等相互作用过程的关系。冰川学与地貌学子项目与其他子项目密切相关，开展系统内反馈的基础研究。通过测量表面消融和激光扫描得到的总体积变化来分离冰下和冰下融化是新的。在厚度约100米的冰舌上进行高时空分辨率的测量是新的，在温带冰舌上使用振动地震来研究冰的厚度和松动带的性质也是新的。
