This article presents assessment methods for the hydromorphological effectiveness of sediment augmentation measures downstream of dams. First, we describe different ways of quantifying hydromorphological effectiveness based on typical objectives of sediment augmentation. Then we show how field observations and physical and numerical modelling can be combined to investigate the influence of design criteria and site conditions on hydromorphological evolution following sediment augmentation. We provide examples of the influence of geomorphic units on bedload transport patterns and the influence of augmentation repetition frequency on hydromorphological variability. The results show that geomorphic units can influence deposition patterns and that consecutive sediment augmentation increases morphological and hydromorphological variability. Finally, we discuss the results and summarize some practical implications.

Designing for impact: a conceptual framework for learning analytics as self-assessment tools

Patrick Jermann, Roland John Tormey, Cécile Hardebolle, Francisco Pereira Correia Pinto

Although it is frequently claimed that learning analytics can improve self-evaluation and self-regulated learning by students, most learning analytics tools appear to have been developed as a response to existing data rather than with a clear pedagogical m ...

Formative assessment

Formative assessment, formative evaluation, formative feedback, or assessment for learning, including diagnostic testing, is a range of formal and informal assessment procedures conducted by teachers during the learning process in order to modify teaching and learning activities to improve student attainment. The goal of a formative assessment is to monitor student learning to provide ongoing feedback that can help students identify their strengths and weaknesses and target areas that need work.

Summative assessment

Summative assessment, summative evaluation, or assessment of learning is the assessment of participants in an educational program. Summative assessments are designed to both assess the effectiveness of the program and the learning of the participants. This contrasts with formative assessment, which summarizes the participants' development at a particular time in order to inform instructors of student learning progress. The goal of summative assessment is to evaluate student learning at the end of an instructional unit by comparing it against a standard or benchmark.

Electronic assessment

Electronic assessment, also known as digital assessment, e-assessment, online assessment or computer-based assessment, is the use of information technology in assessment such as educational assessment, health assessment, psychiatric assessment, and psychological assessment. This covers a wide range of activities ranging from the use of a word processor for assignments to on-screen testing. Specific types of e-assessment include multiple choice, online/electronic submission, computerized adaptive testing such as the Frankfurt Adaptive Concentration Test, and computerized classification testing.
